“I think we probably got used to a degree of absurdity, of outrageous retweets and tweets from the president, but I think this felt like it was a different order,” Cox told CNN’s Anderson Cooper on Tuesday night.

“Here he was retweeting a felon, somebody who was convicted of religiously aggravated harassment of an organisation that is a hate-driven organisation on the extreme fringes of the far, far right of British politics.”

“This is like the president retweeting the Ku Klux Klan,” Cox said.

Jo Cox, Brendan’s wife, was murdered in June 2016 by far-right extremist Thomas Mair. During the attack he shouted “Britain first!,” though it has never been established whether that was a specific endorsement of the group, or a vague nationalist slogan.

Cox spoke to Trump’s temperament in his interview with CNN Tuesday night: “This president has become a purveyor of hate and it’s time we all said enough is enough and we won’t tolerate that no matter what our political disagreements.”

British Prime Minister Theresa May scolded Trump over his retweets, and Trump shot back in a familiar way, using recent terror attacks in that part of the world to snap at May and the UK, one of America’s oldest and most steadfast allies.
